The Kansas City Star reports the federal charges allege that Buckner led others in five robberies this summer, which escalated in violence. On July 16, a couple from Liberty was shot after answering a Craigslist ad for a car.

Police say they tracked Buckner using another Craigslist ad that appeared after the shooting.

Court records indicate that seven of the robbery victims identified Buckner as one of the people who had robbed them.
